SAW-HANDLE.

SPECIFICATION forming part of Letters Patent No. 563,512, dated July 7,1896.

Application filed. April 16, 1896.

To all whom it may concern:

Be it known that I, WILLIAM M. SINGER, a citizen of the United States,residing at Sunbury, in the county of Northumberland and State ofPennsylvania, have invented certain new and useful Improvements inSaw-Handles, of which the following is a specification.

My invention relates to attachments for saw-handles, by means of whichthe handle may be quickly connected to the blade of the saw ordisconnected therefrom without the necessity of inserting or removingscrews or rivets, This attachment may be easily applied to the ordinaryhandle used on handsaws without materially changing its construction.

In the accompanying drawings, which form a part of my specification,Figure 1 is a side view of a handsaw provided with my improvedattachment. Fig. 2 is a similar view, partly in section, and showing thesaw-blade released. Fig. 3 is a perspective view of a plate providedwith guides for the clampinghook and a stop for the butt of the saw, andFig. 4 is a perspective view of the hook for clamping the saw in thehandle.

Referring to the drawings, 1 indicates the handle of a handsaw, whichmay be of the ordinary construction. This handle is provided with theusual kerf 2 for the reception of the butt of the saw-blade 3. A pin orbolt 4 extends transversely through the handle in the lower part of thekerf. The end of the saw-blade is constructed with an inwardly andupwardly extending recess 5, which is adapted to fit over the bolt 4.The upper corner of the saw-blade is also cut away, as shown, so as toform a shoulder 6, and the back of the blade is provided with arearwardly-inclined notch 7 at a point a short distance in front of thehandle.

A metal plate 8, having depending lugs 9 and a transverse abutment 10,is adapted to fit on the back of the saw-handle, as shown in Figs. 1 and2, and is secured to the handle by screws 11 passing through suitableholes. A stop-piece 12 is attached to the under side of the plate andextends downward into the kerf in the saw-handle. On the upper sideSerial No. 587,804. (No model.)

of the plate at the forward end is a guide 13,

in which slides a clamping rod 15. The rear end of the rod is guided ina perforation in the abutment 10. The clamping-rod 15 is screw-threadedat its rear end and provided with a nut 16, and the other end of the rodis provided with a hook 17, adapted to engage the notch 7 on the back ofthe saw-blade. The hook is somewhat wider than the sawblade and isprovided with flanges 18, which extend downward on either side of theblade to prevent thehook from slipping off the blade.

When it is desired to insert and secure the blade within the han dle,thenut 16 is loosened and the clamping-rod 15 pushed forward, as shown indotted lines in Fig. 2. The sawblade is then inserted in the kerf and bytilting the blade slightly downward the bolt 4 will pass into the recess5. The blade is then brought to its normal position,when the shoulder 6will rest against the stop-piece 12. The hook 17 is then drawn into thenotch 7 by tightening the nut 16 upon the clamping-rod. The blade willthus be held between the supporting-pin 4:, stop-piece 12, and the hook17. To remove the blade, it is merely necessary to loosen the nut andtip the blade forward, as shown in Fig. 2.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is

The combination with a saw-blade having a recess 5 in the end and notch7 in the back thereof, of a saw-handle provided in its lower
